Huawei is on the roll. After surprising us with the world’s thinnest Android smartphone with dual-core processor at CES (Ascend P1 S), the Chinese company now announced two quad-core smartphones and one with a dual-core processor at Mobile World Congress. The three devices are part of the new Ascend D series and they all look similar.

The Ascend D comes with TI’s 1.5GHz dual-core processor, while the Ascend D quad and Ascend D quad XL will sport Huawei’s own K3V2 1.2GHz and 1.5GHz quad-core CPUs. Additionally, all three phones feature a 4.5-inch 720p “Excellent Outdoor Display,” HSPA+ and Wi-Fi connectivity, 8-megapixel BSI rear-facing camera with auto-focus (which apparently rocks), 1.3-megapixel front-facing one, 5.1 surround sound with Dolby Mobile 3.0 Plus, 1GB of RAM, GPS, Bluetooth 3.0, dual microphone noise reduction with Audience earSmart technology, 8GB of built-in storage and a memory card slot. The Ascend D quad XL is thicker of the two quad-core phones (10.9 vs 8.9 mm), with the extra space used for a bigger battery (2500 vs 1800 mAh). Moreover, as far as I’ve understood it is also the only of the three Ascend D models that comes with a different sort of plastic on the back, the one that doesn’t make it slippery.

Ascend D quad series will be available in Q2, while the Ascend D1 will start selling at some point in April 2012. Price was not unveiled, though.

Now check out our hands-on photos and let us know what you think about it? You’ll see the Ascend D phones from a number of different angles and also how they compare to other popular smartphones like the Apple iPhone 4S, Samsung Galaxy Nexus, Samsung Galaxy S II and Samsung Galaxy Note. So does the Ascend D series look promising to you? We like it… a lot.
